While Sawant and Moore both trail their opponents, neither race has been officially called. And even if they both lose, they will have received an unusual amount of grassroots and institutional support for two avowedly anti-capitalist candidates running in major American cities. Additionally, they both received major labor union endorsements, and Moore even managed to raise more money than the Democrat in the race.

“This is an indication of how eager people are for real change,” Sawant told msnbc. Both she and Moore ran as members of the Socialist Alternative party, an organization alternatively described as Trotskyist or democratic socialist.

“I think the situation across the country is ripe for this, and our organization Socialist Alternative. What’s unique is our organization took the initiative,” said Moore. “I think in the post-Occupy world, with the political discrediting of most capitalist institutions, including the two major parties, Wall Street, the corporate-owned media—no offense intended—there’s openness to a more bold working class challenge to the two-party system.”

Among the issues Moore campaigned on: A $15 minimum wage, public ownership of Minneapolis utilities, and declaring housing to be a human right. Sawant also focused on low wages and affordable housing as key issues, and was a vociferous supporter of the SeaTac, Wash. referendum that raised that town’s minimum wage to $15 per hour.

Both candidates have a history of grassroots activism outside of the electoral process. Sawant is a member of the teachers union AFT Local 1719, one of six unions to endorse her candidacy. Moore is a cofounder of the anti-foreclosure group Occupy Homes; his campaign was endorsed by the powerful labor organization SEIU Minnesota State Council. Sawant also received the support of a handful of Democratic Party activists under the banner “Democrats for Sawant,” and the endorsement of Seattle alt-weekly The Stranger.

“In fact, we created quite a stir within the labor movement in Seattle and the Democratic Party,” said Sawant. Her campaign says that it managed to raise $110,000 entirely from individual donors.

Bhaskar Sunkara, editor and publisher of the socialist publication Jacobin Magazine, said that a younger generation of voters might be slightly more sympathetic to the socialist cause.

“In general, a lot of young people are demographically a lot less white, a lot of us are first generation or immigrants coming from places where the word has less of a taboo,” he said. “And the Cold War is over.”

Even when wielded by Republicans as an epithet, the “s” word, as Sunkara calls it, doesn’t seem to carry as much weight as it used to. In New York, Democrat Bill de Blasio’s campaign was barely affected by repeated accusations that he was a socialist or Communist sympathizer. De Blasio trounced Republican Joe Lhota on Tuesday with a 49% margin of victory.

“In some ways, I think the right wing has done us a favor” by accusing Democrats of being socialists, said Moore.

But Sunkara cautioned against overestimating the meaning of Moore and Sawant’s campaigns, arguing that they probably do not herald “the coming tide of some third-party push.”

“I think if anything, these are just kind of exceptional examples that we can maybe turn into a generalized trend over the course of years,” he said.

“Our campaigns have shown in a couple small areas how the anger at the present system can be translated into an electoral challenge,” said Moore, “but I don’t think it will be only electoral.” He highlighted the recent fast food strikes as an example of crucial non-electoral organizing.

Sawant said she believed campaigns like hers would spread, but “it’s not an automatic thing.”

“Especially young people of color are feeling a deep sense of betrayal,” said Sawant, herself an Indian-born immigrant. “What have they gotten from society? And they are looking for an alternative, something that speaks to them.”
